*We use low-energy and high-efficiency brand water pumps, and our motors use well-known domestic and foreign brands such as WEG/Siemens/China Brand with guaranteed quality.
*When the cooling tower needs to handle a large flow of cooling water, a single water pump may not be able to meet the system's flow requirements. Using two water pumps can be operated in parallel to provide greater flow and ensure effective circulation of cooling water.
*The water pump can be equipped with a backup pump and a frequently used pump, which can be replaced in a timely manner.
*There are two types of pumps,horizontal pumps and vertical pumps. Vertical pumps are suitable for places with limited space or height restrictions. Horizontal pumps require more space, but are easier to maintain and install in some applications.
Weifang Heng An Group is cooling and heating experts since 1975.We have many cases which replace BAC/EVAPCO/SPX/LU-VE and others famous brand complete machina and spare parts ,our efficiency increased by 30% is from our clients feedback.Except Pump,we also manufacture Cooling Tower/Evaporative Condenser/Air cooler/Fan/Coil/PVC fill/Nozzle/Drfit Eliminator etc.
1 Q: Is your company a manufacture or a trading company?
A: We are a leading cooling tower manufacturer and trading combo with more than 40 years producing experience since 1975.
The famous brand-"Heng An" is well known not only China but all over the world.
As a group company loacted in Weifang Citey of China, we have more than 1000 employees, area of 34hectares and total assets of USD 160 million.
2 Q: What is the difference between a "counter flow" and a "cross flow" cooling tower?
A: The cross flow or counter flow designation characterizes the orientation of the airflow within the heat-transer medium (fill) in the tower with respect to the direction of water flow. In counter flow towers air travels vertically upwards through the fill and makes intimate contact with water droplets falling down through the fill. Hence the air and water travel in opposite directions.
In cross flow cooling tower, the air passes through the fill medium in a horizontal direction, thus crossing the downward water flow.
At same situation, counter flow tower are inherently more efficient than cross flow tower.
3 Q: How do you get repair parts and how long does it take?
A: We have workshop and backup store supplying all parts. 90% of spare parts can be distributed to any plae on the world within one week.
4 Q: What if you don't have the professional engineers to install or maintain the tower?
A: We could dispatch experienced engineer on site to install the towers and train your staff for tower operation and maintaince.
5 Q: How can I choose a suitable cooling tower?
A: If you are available to provide the following information, we can help you to choose the suitable cooling tower.
| Application | Which industry or system using for? For example, HAVC system, casting cooling system |
| Water flow capacity | How many tons of water treatment per hour? |
| Inlet water temp. | Tempreture of hot water to be cooled |
| Outlet water temp. | Tempreture of cooled water, usually it would be at least 3-4 ºC higher than the bulb tempreture. |
| Wet bulb temp. | Highest wet bulb temp. of the location/area or city to install the tower is essential to know to evaluate the size of towers. |
| Power supply | The standard is 380V/3 phases and we have stock. But for customization, the delivery time would be longer. |
